Potential NASA Commercial Applications: Magnetometers are used in a wide array of space science applications. Apart from gravity, magnetic fields are one of the few things we can measure to provide information about the internal composition of planets and other celestial objects. Magnetometers have been carried on almost every space probe/satellite that was headed to another planet, moon or asteroid. Terrestrial and space based magnetometers are used to real time monitor and predict "space weather" which can disrupt terrestrial power stations, telecommunication satellites, global positioning system and other critical infrastructure. Precise measurements of the interplanetary magnetic fields (IMF) provide invaluable information about charged particle and plasma interactions in the solar system. Magnetic fields can provide a natural reference frame in space, and apart from space science missions magnetometers are used by spacecrafts for orientation control, momentum management and scientific instrumentation pointing.
